We describe a novel application for sonic events namely their generation via mathematical functions implemented on a universal all purpose Java platform. Their design is driven by a set of requirements that arise in recognition-based authentication systems. We show that our approach has potential advantages as compared with traditional alphanumeric and other password systems. Our intention is to demonstrate that by leveraging familiar musical dimension and aesthetics human memorability, pleasure and pragmatics are enhanced. We demonstrate and briefly discuss one exemplar generative approach that has been specifically designed in order to fulfill the requirements implied by authentication systems. It is hoped that this work serves to stimulate debate and further activity in the field of computer generated sonics..
